Abstract

1,251,943. Thyristor switching circuits. S. OKUHARA. 3 Feb., 1970 [5 Feb., 1969; 6 March, 1969; 18 March, 1969; 26 July, 1969], No. 5189/70. Heading H3T. [Also in Division G4] In a direction indicating system the direction is indicated by the sequential illumination of a number of lamps, this cycle repeating so long as a control switch is closed. A lamp once illuminated remains illuminated until the end of the cycle when all the lamps are extinguished together. In one embodiment, Fig. 1, for sequentially illuminating three lamps 21, 22, 23 upon successive pulses supplied by a trigger pulse generator 3, each lamp is connected in series with a respective silica controlled rectifier (SCR) 11, 12, 13 across a D.C. source. Initially, none of the SCR's 11-14 conduct. The cathode electrode of diode 31 is not biased and the first trigger pulse reaches gate electrode of SCR 11 and lamp 21 is illuminated. Due to conduction of SCR 11 the cathode voltage of diode 32 becomes zero and thus the second trigger pulse causes SCR 12 to conduct and lamp 22 is illuminated. Similarly, the third trigger pulse causes conduction of SCR 13 and lamp 23 is illuminated. On the fourth trigger pulse SCR 14 conducts and capacitors 61, 62, 63 discharge through SCR 14 causing the voltage of the anode electrodes of SCR's 11, 12, 13 to become negative for a short period whereby the SCR's 11, 12, 13 become non-conducting and the lamps 21, 22, 23 are simultaneously extinguished. However, SCR 14 remains conducting and capacitor 61 becomes oppositely charged so that the anode electrode of SCR 11 is positive and the anode electrode of SCR 14 is negative. When the trigger pulse comes again to repeat the cycle the SCR 11 conducts to illuminate lamp 21 and the capacitor 61 discharges whereby the anode electrode of SCR 14 becomes negative for a short period and SCR 14 becomes non- conducting. Resistors 82, 83 form charging circuits for the capacitors 62, 63, respectively. In a modification (Fig. 2, not shown) the resistors 82, 83 are replaced by resistors (87, 88) connected to the negative terminal of source 1. In further modifications (Figs. 3, 4, not shown) corresponding to Figs. 1, 2, respectively, the resistors 51, 52 are each associated with a normally-closed series switch (91, 92). To indicate an emergency condition these switches are opened whereupon when switch 2 is closed all the lamps 21, 22, 23 flash on and off simultaneously. In a further embodiment (Fig. 5, not shown) the circuit controls two groups of lamps respectively indicating right and left turns, selection of the desired group being obtained by a two-position switch in series with the D.C. source 1. Further, each SCR 11, 12, 13 is shunted by a tell-tale lamp which goes off when the associated SCR conducts.
